Translation of a submission from Banco Macro to the CNV dated on April 8, 2025.

City of Buenos Aires, April 8th 2025.

CNV/BYMA/A3 Mercados

Re.: Relevant Event.

Dear Sirs,

Please be advised that on the date hereof, BANCO MACRO S.A. has been given notice of a class action complaint filed against it and entitled "Protegiendo al Consumidor P.A.C. vs. Banco Macro S.A. on Recovery of Amounts Paid" (Court File #27668).

Plaintiff argues that when calculating the default interests applicable to users of credit cards issued by the Bank, the Bank applies the provisions under Section 20 of Decree No. 70/2023, which is unconstitutional. In this sense, Plaintiff requests the reimbursement of the amounts collected by the Bank to all users and consumers in the Province of Buenos Aires as default interests pursuant to the provisions of Section 20 of the Decree No. 70/2023, in excess of the assessment method provided under the original wording of Section 18 of Law 25065, plus applicable interests and legal costs.

The complaint was brought and is pending before the Court in Civil and Commercial Matters No. 14 of Mar del Plata.

Banco Macro S.A. deems there is low probability of getting an unfavorable court decision in this dispute, and even if that were the case, such unfavorable decision would not have a material impact on its assets.

Sincerely,

Jorge Francisco Scarinci

Head of Market Relations
